This is a Java source code for a simple graphical application that demonstrates how to use various types of borders in Swing, a Java GUI toolkit. The program defines a class BorderDemo that extends JApplet, a Swing component used for embedding a Java application in a web page or other container.

In this java code, a method make(Border border, String command) is defined to create a new JLabel with the specified Border object and text label. This method is called multiple time, each time with a different type of border and a label describing the border. The borders are created using the BorderFactory class, which provides convenient methods for creating various types of borders in Swing.
